Omron LY3-AC120 General Purpose Relay

This Omron LY3-AC120 general purpose relay has plug-in or solder terminals, mounts to a standard bracket, and is suitable for use in low current applications. This relay has a triple-pole, double-throw (3PDT) contact configuration, a load current rating of 17.3 mA at 50 Hz and 14.8 mA at 60 Hz, and a load voltage rating of 120 VAC at 10 amp. It has an 11-pin terminal for connecting to a socket or soldering to contacts, and it mounts to a standard bracket on an equipment rack. This general purpose relay has a compact design and is suitable for use in installations with limited space.SpecificationsContact form3PDTLoad current rating17.3 mA at 50 Hz14.8 mA at 60 HzLoad voltage rating120 VACDielectric strength2,000 VACNumber of pins11Operating temperature-25 to +40 degrees CEnclosure dimensions*28 x 31.5 x 36.5 mm (H x W x D)Standards metUL (Underwriter's Laboratories)CSA (Canadian Standards Association)*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system. Omron manufactures and distributes electronic components, equipment, and systems for industrial automation. The company, founded in 1933, is headquartered in Kyoto, Japan.
